I have recently bought a LaunchPad 2553. I am a comparitive novice.
I am trying to add a 4 X 4 matrix keypad. I copied some code from an Arduino source and changed #Arduino references to #Energia. I commented out a #WProgram statement - what is this ?
The code compiled and verified OK . I connected the 8 wires from keypad to p1.0 -p1.7 [ and tried other ports as well ].
The output was sent to the Serial monitor via Serial.println( key ). I could only get any output by pressing many keys at the same time.
I looked at the keyboard.h file but it went nothing to me. How do the DigitalReads get initiated ?
[ Serial.println ("hello world " ) worked so the program does get to the right place ]
Any suggestions please - pointers to existing code snippets - I can't fine any . Thanks
